Is adjunction of advanced platelet-rich fibrin (A-PRF) useful in first metatarsophalangeal joint arthrodesis? A retrospective cohort study.

Purpose: First metatarsophalangeal (MTPJ1) fusion represents the gold standard treatment for end-stage hallux rigidus (HR). The aim of this study was to assess efficacy and safety of A-PRF in promoting union after MTPJ1 arthrodesis. Our hypothesis was that the use of A-PRF may reduce the non-union rate and the time to fusion in the treatment of HR.

A prospective pilot study of the T-lymphocyte response to fine particulate matter exposure.

Exposure to air pollution is associated with increased morbidity and mortality. Once the fine atmospheric particulate matter (FP) is inhaled, some of its compounds can pass through the lungs and reach the bloodstream where they can come into contact with immune cells. Exposure to FP particularly affects sensitive populations such as the elderly.

Cryotherapy With Dynamic Intermittent Compression Improves Recovery From Revision Total Knee Arthroplasty.

Background: The goal of this study was to assess the efficacy of cryotherapy with dynamic intermittent compression (CDIC) in relieving postoperative pain, decreasing blood loss, and improving functional scores after revision total knee arthroplasty (rTKA).

Methods: We conducted a prospective case-control study (level of evidence: I) to evaluate the efficacy of CDIC on postoperative bleeding, pain, and functional outcomes after rTKA. Forty-three cases were included at a single institution and divided in 2 groups: a control group without CDIC (n = 19) and an experimental group with CDIC (n = 24).

Is the prognosis the same for periprosthetic joint infections due to Staphylococcus aureus versus coagulase-negative staphylococci? A retrospective study of 101 patients with 2-year minimum follow-up.

Background: Staphylococcus aureus (SA) and Coagulase-negative staphylococci (CoNS) are often responsible for infections of total hip arthroplasty (THA) and total knee arthroplasty (TKA). One of the main differences between these two microorganisms is their virulence, with SA presumed to be more virulent; however, few studies have specifically investigated the impact of this virulence. This inspired us to carry out a retrospective study to evaluate whether the healing rate differed between SA and CoNS infections.

Patient information ahead of anterior cruciate ligament reconstruction: Experience in a university hospital center.

Introduction: Patient information is the requisite first step in securing informed consent ahead of surgery, and is legally mandatory. The study hypothesis was that this information is deficient in a significant proportion of cases. This was tested on a clinical audit.
